Abstract: In this work, a metamaterial absorber is designed with the concept of step impedance resonator (SIR) structure for solar cell applications. The rate of absorption can be improved with the use of metamaterial. The designing concept of the metamaterial and the medium is very important when more efficient properties are needed. This proposed design has the capability to increase the absorption rate over a range of frequency 470THz to 570THz and getting the peak absorption at 520THz. This is a unit cell, consists of three layers, which is the substrate, the intrinsic material and also it consists of the top conducting layer which is filled with other materials. The metamaterial absorber is designed and its parametric study is done in the overall range of frequency 450THz to 750THz with various dimensions and filling materials. The materials like silicon dioxide (SiO2), gallium arsenide (GaAs) and aluminium nitride (AlN) are used as the filling materials with the top conducting layer as it is designed in such a way that can provide better absorption rate. And the variations are represented with the help of absorption and reflection parameters.
